B-iTRF: A novel bio-inspired trusted routing framework for wireless sensor networks

In this paper, we present a novel bio-inspired trusted routing framework (B-iTRF) which composed of trust mechanism and routing strategy. For trust mechanism, B-iTRF monitors neighbors´ behavior in real time and then assesses neighbors´ trust value based on the priori knowledge. For routing strategy, each node finds routes to the Sink based on ant colony optimization. In the process of path finding, B-iTRF senses and calculates the metrics of the found routes to support the route selection. Moreover, B-iTRF also assesses the availability of route based on Physarum autonomic optimization to maintain the route table. Simulation results show that B-iTRF can achieve the effective performance compared to existing state-of-the-art algorithms.
